An interactive whiteboard to demonstrate rotation around a point to your class on an IWB. The small black cross is fixed as the point of rotation in the centre of the screen. Click the red shape to move it around the screen. On release it will snap to alignment. Clicking and dragging the vertically aligned slider to the right will take the shape through its rotation around the centre point. Releasing the slider will snap it to the nearest 90 degree rotation.
You can choose between rotating a square shape or an L shape using the button below the slider. The button with a circle toggles the path of rotation on and off. The four pale blue discs canbe dragged and dropped to mark key points. For example you could mark the original top left corner of the shape and where it is expected to be after a 90 degree rotation.
A printable resource is also included for students to cut out and predict what they will think will happen during different rotations.
